MP3 FILESIN MISSION AND MINISTRY

WHY MP3 FILES?• MP3 files work on nearly all computers, phones, tablets, etc• They can be listened to while working on other things or while

stuck in traffic• People are familiar with them, and with downloading them• They are more private than video, if headphones are used• Suitable for oral learners / non-readers / storying cultures• Use much less bandwidth / storage than video• Far easier to edit than video• Contain the same information as video for sermons etc

The Mobile Bible College

Curriculum on an SDHC cardA mobile phone + speakersDoes not need reliable electricity Does not require Internet accessPortable, secure and looks normalCan train up to 25 peopleUseful for house churchesWorks with most types of phones

SDHC cards: 8Gb will hold up to 500+ hours of reasonable quality audio

30 hrs lecturing = one bible college subject (with some class discussion of the material)

So therefore 500 hrs = 16 subjects = 4 semesters of 4 subjects = 2 year course on a fingernail-sized chip
